For anyone that lives in the Chattanooga area.

Don't know about Tn, but the battlefields in Va are open, though I'm not sure about the visitor centers. I know the visitor center at Bull Run had been closed, but I haven't heard if they've reopened. You can go to the National Parks website and see if they're open in Tn. Hotels you'll have to do your own search.

Yeah, definitely check the website of each property you're thinking about visiting. They may vary and I think it will depend on the land manager. If it's a federal property (e.g. NPS) they will be on their own schedule by stages - but influenced by the local situation. State and local managed properties will follow the state and local rules, and private or NGO properties may have their own policies.

But the websites should say.
